I bought the Twinkling Treasures necklace to go with some earrings I already owned (from another company). The earrings look like Christmas tree bulb lights, and flash. The Twinkling Treasures necklace has a better design feature in having a switch to turn the necklace on and off. However--- finding the batteries was a real Grail Quest. When I finally ran them down, I could only get the at Radio Shack, for about $15.00. This year I decide not to spend the money on batteries, and simply wore the necklace, which is still cute. The necklace kept droppong bulbs. I ended up having to throw it in the trash. It was fun for a season -- I'd like to find a better constructed replacement, which would use more affordable (and easier to find) batteries.
